Sorry - only seeing this reply now.
Can you give me a bit more detail on the way an app would be designed to pass data to/from the game engine…not the actual code but the basic steps ?
Some people have suggested using OSC…I have never come across Bonjour. I presume all protocols would involve plugin for unreal.
I presume the app would need to be written in xcode ?
If the app is pre-packaged is there anyway to communicate with it or does a new app have to be coded ?
Are there any resources or sample files online or on the forum for this type of work ?
